Asked if it's been a good business for him, Knight laughed, "Yeah sure, my wife bought a new car!"

Knight noted that he tends to sell more than one plaque every day, with customers seeking him out from far and wide, thanks to attention he has received over the years in many publications and broadcasts.

In October, spiders aren't terribly active, but in the warmer months, Knight hangs frames in his barn and waits until spiders make webs in the holes of the frames. To encourage web-weaving, Knight and his wife look for spider egg sacs throughout the season, and relocate those sacs to the frames.

After the spiders weave their webs, Knight explained he takes spray paint and sprays the webs white. Finally, in the most delicate step, he takes a plaque and pushes it through the hole to harvest the web. A shellacking process then further preserves the webs.

So why the attraction to webs, in the first place?

"I have more respect for nature than I do for a lot of my neighbors," Knight said, laughing. "I appreciate nature."
